Initial legacy software investigation
Find out whether one blocked change can be made safely.
A five-working-day investigation for organisations that need a valuable change but do not yet trust an existing PHP application enough to make it safely.
A focused first step
One valuable change is stuck because the existing application is hard to trust
- The business outcome is clear enough to investigate
- The work concerns one PHP application running on Linux
- The application contains up to 300,000 lines of first-party PHP code
- Third-party packages, generated code and minified assets are excluded from that limit
- Controlled source-code and database-structure access can be authorised
Larger codebases, multi-application estates and implementation work require a tailored scope.
Defined first engagement
One change, one application, five working days
The investigation focuses on one commercially valuable change in a qualifying PHP application running on Linux.
This is an initial offer, not a universal fixed price.
£1,875 five-working-day investigation
- A clear finding about the blocked change
- The risks that matter, in priority order
- A separate quote for implementing the improvement
- No live production access required
Before work begins
Scope, access and safeguards are agreed first
The investigation starts only after the blocked change, application boundary and required access are clear.
- The business change and why it matters
- Controlled source-code and database-structure access
- Confidentiality and permitted AI tools
- Any data-handling or supplier constraints
AI assistance is paired with experienced human review, practical testing and accountable engineering judgement. AI tools are not given production access.
What you receive
A decision-ready route forward
The investigation turns uncertainty about one blocked change into a clear finding and a practical next decision.
You receive the finding, the priority risks and a separate, evidence-based quote for implementing the improvement. Implementation is outside the five-day investigation and is scoped separately.
If the application, codebase or change does not fit this defined offer, I will identify the need for a tailored scope before work begins.
